Why the Nelson-class triple turrets needed refinement

Were the Nelson-class turrets improved after their early reliability problems?

Yes. Most faults had already been worked through before 1937, after difficulties caused by introducing the Royal Navy's first triple turrets and then lightening and reworking the design.

The answer presents unreliability as a development problem rather than a permanent class defect. The Royal Navy was putting its first triple main-battery turret into service while also revising an established concept to meet weight constraints. Numerous small changes gradually made the machinery workable, illustrating the risk created when novelty and aggressive weight reduction arrive together.
